Divergent responses to drought conditions : rice-growing in three Jola communities of Casamance, Senegal
To understand the impact of drought upon an agricultural system it is essential to have detailed, base-line data on local community land-use and labor practices before drastic ecological changes set in. Empirical research of this kind is rare, but it exists for a Jola village in Casamance, Sénégal. In 1964, the author mapped the total rice-fields owned and worked by the inhabitants of a Jola village called Jipalom. The map covered 29 ha of nursery and rainfed rice fields (the yentamsg/ seentampl.) and 3,81 ha of tidal, brackish-water fields (the weng). It included more than 3 000 separate parcels belonging to 20 male household heads and worked by their 28 "active" wives, plus 3 "retired" old ladies, all using additional group- labor. The map then served as a basis for collecting information on local field categories, land- tenure principles, labor investments, rice varieties, cultivation techniques and harvesting procedures throughout the entire agricultural season of 1965. Subsequently, the map data was monitored in the field for land use changes during the 1970's-1990's. Using a computer project designed by P. Garnier, the map and its associated information has provided a base- line against which to measure and interpret land-use changes throughout the years of drought. In this talk, Linares and Garnier illustrate a computer-based methodological approach that combines graphic data on cultivated surfaces with a rich corpus of quantitative information.
